In summary, Louise Riofrio's density fractions for baryonic, dark matter and the remainder are given by

$\Omega_b = 1 - \frac{3}{\pi}$, $\Omega_d = \frac{3}{4 \pi}$, $\Omega_r = 3 \Omega_d = \frac{9}{4 \pi}$

and the total density is $\Omega = 1$. The number $\Omega_d = 3/(4 \pi)$ characterises all three densities, showing that Riofrio's law of pair creation and annihilation governs the mass energy content of our universe.

Thanx again for the linx! We have enough faith in math to believe that truth will win out.

ReplyDeleteYou are most welcome, Louise. At this rate, truth will win out only long after we are gone.
